sel for Chemicals, of which the following is a full, clear, and exact description.

. This invention relates to vessels; and it consists, substantially, in the features of improvement hereinafter more particularly described, and ointed out in the claims.

T e invention has reference more especially l to glass or similar vessels, as bottles and jars, for instance, of the type (embodyin removable lids or covers) employed by c emists, dealers, and consumers for contaming chemicals, and which require to,be opened from time to time for the purpose of emptying the same of some portion ofthe contents thereof, accordin to the amount required for use or when ma in .a sale. f

As is wel nown by chemists and others, when certain chemica s are put up in lass or fsimilar vessels, as bottles and jars, un ess effective seals are provided between the mouthsof the vessels and the closures therefor the contents ofthe vessels soon become so contaminated as to be rendered unt for use and which of course results ina dead loss. Vessels for this purpose were formerl provided with seals or closures of cork; ut as cork is gradually becoming inferior and more expensive and on which account it became necessary to construct the necks (and conseuently the mouths) of the vessels considera ly smaller than before it follows that more time is now consumed both in iillin the vessels and in emptying the same of t eir contents. Moreover, cork by reason of its structure or nature (being crous) readilyT absorbs or becomes filled with) substances which are apt to be detrimental to the contents of the vessels, as will be understood.

One of the principal objects of the present invention isvto provide a chemical-containfl'ng vessel of the type referred izo/comprising means between the mouth and closure therefor for effectuallv reventing contamination 4 of the contents of t e vessel either by access of air to the vessel or by contact of the contents thereof with such means, substantially as will hereinafter more fully appear when taken ini connection with the accompanying drawings,

in which similar characters of reference indicate'ccrresponding parts in all the figures.y

Figure 1 is a sectional view illustrating one embodiment of my improvement. Fig. 2 is a similar view representing a mmlicaticn of the embodiment shown in Fig. 1. Fig. 3 is a sectional view representing another embodimentcf my improvements. Fig. 4 is a similar view representing a modification of the embodiment shown in Fig. 3.

Before proceeding with a more detailed description it may be stated that with some of 4the embodiments of my improvements herein shown I employ a specially-constructed closure for the mouth of the vessel, between a member of which and the edge of the rim of the vessel at the mouth I em loy a special outer so-termed seal which not only serves its function as such, but which also serves to securely fasten the closure to the vessel in such manner as to prevent the same from working loose or becoming detached therefrom during shipment or transportation of the vessel.

In each of the embodiments of my improvements herein shown I employ between a part of the closure for the vessel and the upper surface of the rim of the mouth of the vessel a special inner (so termed) seal, which also not only serves its function as such, but which besides serves to retain the closure in place each time the same is applied to the vessel after being temporarily removed therefrom for any purpose.

In other embodiments of my improvements herein lshown I em loy'a further s ecially-constructed closure fdr the mouth o the vessel, in association with which may be employed either the special outer or inner (or cth) seal above re erred to, and in connection wth this special closure I also employ still another special inner seal, which admirably adapts the vessel with which the two (this closure and seal) are employed as a container for ceftain chemicals, as bisulfite of soda, copper nitrate, and the like.

In each embodiment, and especially with the form of closure last referred to above, the seal em loyed is preferably constructed of a materia or substance not readily attacked by the particular chemical containedin the vessel, as inorganic non-metallic substances or other substances impregnated therewith. Thus in the one case the seal may be con- IOO which the inner seal first referred to above shall possess the quality of adhesion.

The closure for the vessel may be constructed of lass or othernon-corrosive material or, in view ofthe thorough effectiveness of my improved seals for the vessel, the same could be made of lead, tin, porcelain, asbestos, soapstone, or an other desired material. Said closure 'may aso be of rounded, fiat,

concave, convex, or any other desired shape. exter1orly, las will be a parent.

Reference bein ha to the drawings by the designating caracters thereon, 1 represents a-containing vessel for chemicals, as a bottle or jar, for instance, the same having a neck 2 provided at the up er outer edge of the mouth of the vessel witli an outwardlyextending rim 3 of suitable depth or thic ness, which is preferably ground off perfectly fiat or even, so as to be entirely devoid of crevices or recesses, in which any parti'cles of the chemicals within the vessel mi ht lodge. A

is shown in Fi 1, the vessel 1 is provided with a closure 4 1n the form of a removable lid or cover having an annular depending flange 5, the internal diameter of whichis considerably larger than the external diameter of the rim 3 at the mouth of the vessel, as shown, thus forming an annular space between the adjacent faces of said rim and flange'whenthe closure is properly seated in place. Seated upon the up er surface of the said rim 3 at the mouth of tlife vessel is a sealin -ring 6, formed of any of the materials or sustances mentioned above as employed therefor or any combination of said materials or substances, but which may be referred to at present as paraffin, said sealingring bein constructed to accurately fit the upper s ace of the rim and constituting the inner seal for the vessel first referred to above. The inner surface portions of'the closure 4,'corresponding with the said upper surface of the rim 3, are also preferably ground perfectly -fiat or even, so that when said closure is applied in position over the mouth of thel vessel, as presently explained, the contents of the latter will be prevented from contamination or becoming deliquescent. ln first filling the -vessel, say, at the factory or laboratory the annular space between the adjacent faces of the rim 3 and flange 5. is filled with a seal 7, formed of a material-say rosin, for instance-preferably possessing greater tenacity or adhesive roperties than the material of the sealing-rm 6, thus to securely hold the closure in p ace durin r shipment or transportation of the vessel. his seal 7 is the outer seal referred to above, and the material thereof may be readily poured into the space between the rim 3 and flange 5 after first applying the sealing-ring 6 to said rim and fitting the clo- .sure thereupon with sufficient pressure to :cause adherence of said ring toboth the rim and the corresponding inner surface portions of said closure. When this has been done, the vessel and its attached closure may beinverted to receive the material of said outer seal 7 withoutliability of the closure falling off. Whenever the chemist or dealer first desires to use any of the contents of the vessel, he breaks or removes the seal 7, and then by pulling upon the closure with sufficient force the latter may be readily removed without in any manner disturbing or im airing the sealing-ring 6, and then after ta g from the vessel as much of its contents as may be required the closuremay againbe a lied to the vessel in such manner as to fie 4 eld thereon during the ordinary handlin of the vessel or when placed upon the shel 4simply by the adhesion of the sealing-ring 6 to said rim and said closure; Prior to shipment of the-filled and sealed vessel, as above described, the closure and neck of the vessel may in some instances be immersed in a solution of araffin, sealing-wax, or the like in.y order to urther seal the contents of the vessel against injury; but this is merely optional in ractice.

shown in Fig. 2, the spacebetween the adjacent faces of the rim 3 and flange 5a of the closure 4 is considerably less in width than the corres ondinor s ace in Fi 1 and P a F g i the same is preferably fil rim 8 of the inner seal 9, which corresponds to the sealin -ring 6 of Fig. 1, formed of paraflin or the ike, as explained, this embodiment of my improvements not necessarily involving the .use of an outer seal of a more tenacious character, as in Fig. 1L

'In Fig. 3 the closure 10 is provided with a depending flange 11, and between the upper surface of the rim 3 of the vessel and the corresponding surface portions of said closure is located aninner sealing-ring 12 similar to `the sealing-ring 6 in Fig. 1, the space between the adjacent faces of said rim andv flan e 11- ed by the` pendent ITO being Fpreferably filled wth an outer sea 12a,

as in g. 1, formed of a material the tenacity or adhesive properties of which are greater than the material of said inner sealing-ring 12. In this embodiment of my improvements I construct the closure 10.with a stop,- per 13, extending within the neck 2 of the vessel for any desired depth and the exter- Inal diameter of which is less than the internal diameter of said neck, thus to provide a space I yO closure is considerably less in widt .made integral with each therebetween suficient to accommodate `a tubular additional inner seal 14, formed of any of the materials or substances hereinbefore mentionedl as employed therefor, the lower end of this seal being closed, as indicated at 15, to prevent contact of the contents of the vessel with said stopper. With this embodiment the closure may be operated, -as already described with reference to Fig. 1, as will be ap arent.

Fig. 4 the construction is substantially identical with that of Fig. 3, with the exception that thes ace between the adjacent faces of the rim 3 of) the vessel and iian e 11 ofthe as in Fig. 2, and is filled or occupied by the pendent rim 16 of an inner sealing-ring 17 similarly as the corresponding space in Fig. 2 is occupied by the said pendent flange 8.

As shown in Figs. 3 and 4, the sealing-rings 12 and 17', respectively, are made separate from the tubular seal for the.l stopper of the closure; but in some instances the two may be other and still subserve their intended functions.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A container for chemicals, comprising a neck, a closure having a depending ange spaced apart from the neck, a' sealing device between the edge of the neck and the closure,

and a second sealing .device between the ange and the side of the neck.
